apt-get update/upgrade

Red Squirrel · 07-11-2005, 07:45 PM

I ran an apt-get update and apt-get upgrade to see if any of my software has newer versions, and it's installing a HUGE amount of stuff in my system. It's beeing going on for almost half an hour. Is this normal? I was also promped for really weird stuff I had no clue what it was talking about, so I just hit cancel, but the install keeps going on. I just hope this won't trash the system since I did not image it before doing this. I figured it would of only did what it usually does and upgrade a few packages here and there.

It can be very normal, in a new install or one that has not had apt-get upgrade done recently. It may trash your system, but it is not likely unless you are running sid (and even then it isn't that common).

Red Squirrel · 07-11-2005, 07:54 PM

Only noticable thing is after the reboot it said my /etc/fetchmailrc file was missing. But that's because I got the error, I just hope nothing else did not get deleted. I think I'll put one of my sys backups asside just in case...

SHIT! It freaken blew my mail server... that's the most complicated thing to setup too. this sucks... I know not to do an apt-get upgrade again... It just randomly does stuff to the system without my knowledge. That's not cool.

Is postfix an SMTP server? Since I use dovecot as my smtp but noticed postfix is running. I can't remember if it's suppost to be running or not, mail is probably one of the most confusing protocols due to the amount of server apps required for it to work, so I just don't know anymore what's suppost to be running.

Pcghost · 07-11-2005, 08:09 PM

apt-get upgrade without arguements like package names, updates every package on the system that has a newer version available. Before getting too deep into debian system administration, you really should read the apt-get how to.

http://www.debian.org/doc/manuals/ap.../index.en.html

Postfix is a mail server, and a good one in my opinion. See http://www.postfix.org/

Start at the beginning. What is the job of this server?

Red Squirrel · 07-11-2005, 08:14 PM

I know it's a mail server, but what does it do, SMTP or POP3? Since I think I have two SMTP servers running and they're running into each other. That's how it was when I first installed debian and I had to delete one from all the rc folders, took nearly a week to get it all cleared out since there was so much junk it had to startup. But according to ps aux dovecot is running, maybe the upgrade botched the config file the same way it tried to do to my smb.conf file, but I happened to have it open in vim so I just made sure to save it again. I think what this "upgrade" did is change all the config back to default. All I can say, I'm definatly not trying that trick again.

Pcghost · 07-11-2005, 08:18 PM

Once the downloading phase of an apt-get upgrade is complete, you should see a bunch of questions asking whether you want to keep your version of the config files, or use the developers versions. I think that is where you hit cancel.

A better way of reducing the clutter. You have a mail server dovecot right? So you don't need postfix, or sendmail, or exim so you type the following at the prompt.

apt-get remove postfix
apt-get remove sendmail
apt-get remove exim

That will get rid of the conflicting mail servers, or any other package you want rid of.

To find out which version of debian you are running, type the following

cat /etc/apt/sources.list

and look for the words

Sarge (or Stable)
Etch (or Testing)
Sid (or Unstable)

Those are the three current versions of Debian. The first two are subject to change, but not very often.

Oh yeah, and fetchmail is a pop3 mail retriever, Sendmail, Postfix, and Exim are SMTP servers.

Red Squirrel · 07-11-2005, 08:26 PM

Crap that question again, what is it talking about?! All I want to do is uninstall postfix.

Code:

 Locale is a framework to switch between multiple languages for users who  x  
 x can select to use their language, country, characters, collation order,   x  
 x etc.                                                                      x  
 x                                                                           x  
 x Choose which locales to generate.  The selection will be saved to         x  
 x `/etc/locale.gen', which you can also edit manually (you need to run      x  
 x `locale-gen' afterwards).                                                 x  
 x                                                                           x  
 x Select locales to be generated.

It's in one of those blue/gray dialog boxes and it has a weird list like this:

[ ] aa_DJ ISO-8859-1 # x
x [ ] aa_ER@saaho UTF-8 a x
x [ ] aa_ER UTF-8 a x
x [ ] aa_ET UTF-8 a x

That goes on for miles

It also screwed up dovecot, since even when I start it, it wont listen on any port. Is there a way to reverse all this mess?

Pcghost · 07-11-2005, 08:32 PM

Dovecot probably can't bind to port 25 (if it is an SMTP server) because one of the other mail servers has it. The locales question would be easier to help you with if you put your location in your profile. It wants to know where you are so it can gear things for your location. Look down the list for your countries initials.

Red Squirrel · 07-11-2005, 08:35 PM

But why does it need to know where I live and what is it going to do? All I want is to delete postfix, as it will be faster then having to delete all the entries in the /etc/rc[x] folders like I had previously done at first. But even with postfix killed, dovecot still won't run. If I remember well, I had to edit some host file to allow IPs to relay, and the "upgrade" probably deleted that file too... with my luck, the backup most of ran right after since I can't find any of the missing files, and for some reason the backup of /etc/ was not set to rotate on a period of 5 days like all my other backups...

Pcghost · 07-11-2005, 08:40 PM

It needs to know what language you use etc, because it is trying to finish the locales installation you triggered by upgrading the entire system. Answer it and it will go away.

Is there an error when you start dovecot? What does /var/log/messages say?

You need to take this slower. I know how it feels to have a configured server go south, but it will only make things worse if you panic and rush through this. Once the other packages that downloaded finish their upgrades you will be back at a prompt. Then you can get things fixed. Until then just try to read and answer each of the questions, they will only ask them once.

Red Squirrel · 07-11-2005, 08:49 PM

No errors, it just does not listen on the port at all. Now that I think of it, I rather not uninstall postfix because it has a sendmail replacement which php mail() uses... well I never got php mail() to work but at least it's there for if ever I managed to get it working.

Oh and btw my debian version is SARGE, if it helps.

Red Squirrel · 07-11-2005, 08:56 PM

I'm trying to install exim to see if I get luck... at this point, I don't care what smtp server I have, as long as I can send mail, and really it's even stopping me from receiving as fetchmail uses smtp to deliver to the mail boxes.

But even exim is asking me that locale question. What am I suppost to put? It's just a bunch of weird packages, I have no clue what to put, and I assume if I put the wrong one it will install some other language then English. I don't even know why it needs this, I always figured a mail server handled mail in "raw" mode, not caring what language it's in.

Pcghost · 07-11-2005, 08:57 PM

Run ps -A and see if it (dovecot) is running at all. Also look for smtp or postfix/sendmail etc. If nothing is listening on port 25 (telnet to the external ip at port 25 and type HELO) then try to start dovecot again. When/if it fails type tail /var/log/messages and see if dovecot is mentioned.

One more thing on package management in Debian. If the command-line apt-get is a bit much for you at this point, and you have a GUI installed on the server, type apt-get install synaptic and get a very cool front-end for apt that will make that a lot easier on you.

Red Squirrel · 07-11-2005, 08:59 PM

dovecot runs, but can't connect to 25 externally or locally, If I do a netstat -la, same thing, nothing listening on 25. It's really messed up.

Just realized, dovecot only stays in memory for a bit then terminates, since later on it won't show up in ps aux anymore.
